I'm starting to see painted gas lines on newer commercial roofs. Never in residential or older light commercial.

The only place I have seen any painted was in a govt building. We have a shopping mall with 100 RTU's and all gas pipe on roof, miles of it some most is high pressure all the units have separate regulators. No paint. I guess things are more strict in other places.

It's not strict around here, the places I've seen them is on new walgreens and comparable chain stores done by national companies. None of the local contractors paint gas lines.
